Abstract:
Objective To design a system for the detection of coagulation factors using piezoelectric quartz crystal (PQC) sensors and to introduce its operating principle and the main components. Methods The contrary piezoelectric response of quartz crystal was used. Based on the fuzzy and decoupling control, a singlechip computer was used for constant temperature and constant humidity control and frequency count. The plasma coagulation time was measured for the purpose of determination of the activities and contents of the coagulation factors. Results The system was convenient, precise, and consistent for the detection of the coagulation factors. Conclusion PQC sensors with high accuracy and low cost can be used in the detection of coagulation factors and has a bright future in clinical practice.
